The DNS server on the Chromebook is yet another potential problem. A DNS server translates domain names to host Internet Protocol Version addresses or manual IP addresses. You cannot access the internet if the DNS servers are down, and DHCP connection issues can also be due to an outdated operating system or poor office network, but you can go for the option reset settings and use an ethernet cable for a good internet connection; change previous DNS settings if there is still the error.
